For 55 years, the New Britain Goshawk, or Accipiter princeps, had not been seen which left many ornithologists to presume the rare bird of prey was lost. As a result, the elusive bird — which had never been photographed before and was only known to science from four specimens — was categorized as “vulnerable” on the IUCN Red List of Threatened Species.
